Virtual Shelf


The Virtual Shelf Module is a commonality tool that assists shipyards (both private and government) in locating common parts used across hull classes and within the fleet. Virtual Shelf allows users to search for parts by category and specification. Allowing the user to see and compare existing components for use in their designs. The comparison is done on both commercial and specialty parts purchased for the Navy. The search ability is designed to Reduce Total Ownership Costs (TOC) for new acquisition/modernization programs. This is achieved by allowing engineers, designers, and planners the ability to find existing approved components for their applications.

Virtual Shelf contains a catalogue of parts used in the shipbuilding, repair and refit procedures.

  • i.e. motors, valves, watertight doors, nuts and bolts, etc.
  • Logistics Support, Obsolescence, Maintenance and Repair, Operating Costs
  • Sliders allow for varying cost estimations based upon the expected lifecycle of a part

Virtual Shelf Users

Deep Dive Team

The commonality team from NSWC Philadelphia performs deep-dives on all of the part categories to develop classes of parts. Gather data from the shipyards and import the data into Virtual Shelf. The analysis and configuration management is performed within the Virtual Shelf Module. After this analysis, a list of parts is published for the entire Virtual Shelf community.

Standard Virtual Shelf User

Engineers, Cost Analysts, Program Managers, Ship Design Managers, Logisticians, etc. Functionality varies across these user roles. Core functionality includes viewing the common parts for all of the parts categories. Users are also able to view the specifications for these parts.

Advantages to Virtual Shelf

Virtual Shelf reduces processing time for Deep Dive teams by performing real-time calculations and allowing users to custom configure any part or system. This analysis can be performed on a part, system, ship, class, or fleet, and reduces processing time by months. Uses cost analysis as well as commonality in calculations and helps find synergies to reuse existing and commercial systems in shipyards.

Users are able to perform advanced filtering to find a range of parts that suit their needs. Filtering capabilities allow users to find the most cost effective part that meets the desired application.

Release Virtual Shelf to Production on February 26, 2019. Virtual Shelf development doesn’t stop at this date. New functionality and changes to occur under the CSR process and align with PDREP’s regular production releases. Integrate with existing part and material data already in PDREP.
